Name: Sarcobatus vermiculatus / Bouteloua gracilis Shrubland Reference: Western Ecology Working Group of... Description: This poorly documented association has been described only from north-central New Mexico, along the Rio Chama, a tributary of the Rio Grande. This is a semi-arid region, with annual precipitation of 25-35 cm. Most occurs as the result of high intensity, short duration, convective thundershowers during the summer months. Summers are typically hot, and winters are moderately cold, with some snowfall. This association is found on alluvial fans of drainages emptying into the northern side of the Rio Chama, at about 7000 feet elevation. Slopes are gentle. Topography of these sites is such that water tends to spread out and flow slowly, causing sheet erosion. Soils are likely to be finely textured and alkaline. This is a subdesert shrubland, with a moderately dense layer of deciduous and semideciduous shrubs, about 0.5 m in height. Sarcobatus vermiculatus and Atriplex canescens dominate this layer. A lower shrub layer (20 cm tall) is dominated by Gutierrezia sarothrae. The herbaceous layer is composed of perennial grasses, with total cover of 12%. Bouteloua gracilis has the highest percent occurrence, followed by Pleuraphis jamesii (= Hilaria jamesii) and Sporobolus cryptandrus. Few other species occur.  Accession Code: VB.CC.26954.SARCOBATUSVERMI Plot-observations of this Community Concept: 0
